PORTABLE G RAIN-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 649,103, dated May 8, 1900.

Application tiled January 11, 1900. Serlal No. 1,156. (No model.)

To all whom it may concern):

Be it known that I, WARREN H. GLEAsoN, a citizen of the United States, residing at Chelsea, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Portable Grain-Elevators, of which the following is a specification.

The object of this invention is to produce a portable grain-elevator which may be operated by hand or power, which may be easily transported from one place to another, and so constructed as to be easily repaired or adjusted.

With my improved portable elevator the grain is elevated from the cart in which it is carried to a granary or car with much less labor and loss of time and material than with the method of shoveling.

The invention consists in certain arrangements and combinations of parts, as set forth in the following specification and particularly pointed out in the claims thereof.

In the drawings, Figure 1 is a front elevation of my improved portable grain-elevator. Fig. 2 is a vertical sectional elevation taken on line 22, Fig. 4, looking1 toward the right in said figure. Fig. 3 is a Vertical sectional elevation taken on line 3 3, Fig. 1, looking toward the right in said fgu re. Fig. 4 is a side elevation taken from the right of Fig. 1, the grain-elevating tower being shown lowered to a horizontal position in dotted lines. Fig. 5 is avertical sectional elevation through the grain-bin, taken on line 5 5, Fig. 3, looking toward the right in said ligure, the tower being shown in elevation. Fig. 6 is a detail perspective of the slide-partition which separates the grain-bin from the buckets. Fig. 7 is a detail Vplan section taken on line 7 7, Fig. 1, showing the means whereby the grainelevating tower is locked in a vertical position to the grainbin.

Like numerals refer to like parts throughout the several Views of the drawings.

In the drawings, 10 is a receptacle or bin for the grain which is to be elevated, and 11 is a tower to which is attached the grain-elevating mechanism. The bin 10 is open at the top, has three fixed vertical sides 12 12 12, a bottom 13, and an inclined false bottom 14, which directs the grain toward an opening 15 in the vertical slide-partition 16. Said partition is arranged to be moved in ways 17 upon the sides 12 12 of the bin 10, so that it may be entirely removed from said bin, and thus the `latter may be easily swept and cleansed.

Upon the slide-partition 16 are fastened ways 1S, which guide the slide 19, said slide having a handle 20, whereby it lnay be lifted, the function of said slide being to open and close the opening 15 in the partition 16 and allow the grain to iiow from the bin into the lower portion of the tower 11 orpreventitfrom so doing. The tower 11 consists of a vertical supporting-plate 21, to which is attached the framework 22, consisting of side pieces 23 23 and a central supporting-frame 24, all framed and joined together in a strong and substantial manner. In the lower end of the tower 11 is a pulley 25 and in the upper end another pulley 26, said pulleys being connected to each other by an endless belt 27, to which are attached buckets 28. The upper pulley 26 is fast to a shaft which turns in bearings in hangers 29, said hangers being screwthreaded at the upper ends thereof and supported by hand-wheels 30 30 and set-nuts 31 31 screwed thereon and resting upon a crosspiece 32, supported upon the framework of the tower. By screwing up on the handwheels 30 it is evident that the pulley 26 will be raised and the belt 27 tightened, and vice versa, the side pieces 23 being slotted at 33 to admit this adjustment of the pulley 26. The belt 27 and the buckets 28 attached thereto move in a space 34 between the side pieces 23 and the central supporting-frame 24, said space being inclosed at each side by side plates 35. The lower pulley 25 is fast to a rotatory shaft 36, said shaft turning in bearings in the side frames 23, supporting-plate 21, and bracket V37. The shaft 36 is rotated by a spur-gear 38 fast thereto and meshing a spur-gear 39, fast to the shaft 40, said shaft turning in bearings in the supporting-plate 2l and bracket 4l, and having a bevel-gear 42 fast thereto, by which it is rotated, said bevel-gear meshing a pair of bevel-gears 43 44. The bevel-gear 43 is fast toa shaft 45, having one bearing in a bracket 46, fast to the plate 21, the other end of the shaft linding a bearing in the sleeve 47, to which sleeve the bevel-gear 44 is fastened, said sleeve turning in bearings in the brackets 48, fast tothe IOO plate 21. The crank-handle 49 is fast to the shaft and the crank-handle 50 to the sleeve 47, so that by turning said handles in opposite directions the pulley 25 will be rotated through the train of gearing hereinbefore described, the two handles rendering it possible and convenient for two men to work at the same time, although it is evident that one may operate the mechanism if desired.

The top of the tower 1l is inclosed by a `plate 5l, and the grain is delivered from theV buckets 28 into a chute 52, having a plate 53 fast to the lower end thereof, in which a tunnel 44 is supported by means of a flange 55, so that said tunnel may turn thereon in a horizontal plane. A spout 5G is pivoted to the tun nel 54 and may be locked at different angles by means of the hook stay-rods 57 and staples 58 at different heights upon the chute 52.

At the lower end of the tower ll is a semicylindrical plate 59, which incloses the buckets as they pass around the under side of thc lower pulley, into which the grain flows from the bin 10, through the opening G7, before being taken by the buckets.

In order to make the interior of the tower easy of access, so that the beltin g and buckets therein may be adjusted, repaired, or cleansed, I provide hinges GO GO, one plate of each hinge being fast to the bottom 13 of the bin 10, the other to the plato 2l of the tower l1, so that the tower may be turned from a vertical to a horizontal position, Fig. 4, upon said hinges. The side piece 23 is made removable by means of screws Gl and hooks 62, so that when the tower is in a horizontal position the side piece at that time on the upper side can be removed, also the side plate 85, and the belting and buckets repaired or cleansed with ease and despatch.

In order to lock the tower 11 to the bin IO when said tower is in a vertical position, I`

provide a metal clamp (33, fast to the plate 2l, the ends thereof bent at right angles to form ears (i4, having holes therein through which pins 65 are introduced, and engaging corresponding holes in the plates 66, fast to said bin, and thus locking the tower to the bin. It will be observed that the buckets 28 are fastened to the belt 27 by rivets through the back of said buckets and said belt and that `the buckets are arranged at such a distance from each other that when a bucket h is dumping its contents the bucket c next preceding or below said bucket will close the opening 34 between the side piece 23 and supportingframe 24 and help to guide any of the grain emptied from bucket Z) into the chute 52.

The operation of the device as a whole is as follows: The elevator is placed upon the ground and (supposing the bin l0 to be filled with grain) the slide 19 raised. The grain `flows into the semicylindrical-shaped plate 59, the buckets are put in motion in the direction of the arrows CL by turning the crankhandles 49 and 50, the grain is carried up by the buckets over the pulley 2G and dumped into the chute 52, thence iiowing through the tunnel 54 and out of the spout 5G, and is discharged into a car or granary, as desired.

In order to repair the belting or buckets,v

the pins G5 65 are removed, the tower lowered to the position shown in dotted lines, Fig. 4, by tipping the same upon the hinges GO. The upper side piece 23 and side plate 35 are removed by removing the screws Gl and unfastening the hooks 62, and the buckets and belt then being exposed are easily repaired or cleansed, as may be desired.

Having thus described myinvention, what I claim, and desire to secure by Letters Iatent, is Y 1. In a portable grain-elevator, a series of buckets attached to an endless belt, mechanism for imparting motion to said buckets, a tower upon which said buckets and operating mechanism are supported, said tower consisting of a framework attached to a vertical supporting-plate 2l, a grain-bin 10, and hinges connecting said plate and grain-bin.
